Error: Windows 11 sleep not working

“Hello, I've just bought a new laptop and thus switched from good old Windows 10 to not-so-good Windows 11. For some reason the sleep mode doesn't activate when I close the lid.
The thing is, I've searched this forum and I've done all the things suggested - I opened the control panel and changed the functions of power buttons (I picked 'shutdown' for the main power button and 'sleep mode' for closing the lid), I've restarted the power plan etc. and the problem still persists. Please, help me fix it, I've run out of options.”
